Black Butler, Vol. 1 by Yana Toboso

Just a stone's throw from London lies the manor house of the illustrious Phantomhive earldom and its master, one Ciel Phantomhive. Earl Phantomhive is a giant in the world of commerce, Queen Victoria's faithful servant...and a slip of a twelve-year-old boy. Fortunately, his loyal butler, Sebastian, is ever at his side, ready to carry out the young master's wishes. And whether Sebastian is called to save a dinner party gone awry or probe the dark secrets of London's underbelly, there apparently is nothing Sebastian cannot do. In fact, one might even say Sebastian is too good to be true...or at least, too good to be human...

Yana Toboso is the creator of the wildly popular series BLACK BUTLER which is currently serialized in Square Enix's magazine MONTHLY GFANTASY. Her previous work was a single volume entitled RUST BLASTER.
